Background ideas???

[snibborsirk]

so I have my ~ 2 month old Chacoan in a temp 90 gallon aquarium... Any creative ideas for a good looking background??? Thinking of just doing a plain black or gray background but am looking for creative suggestions. FYI - the "scenic" aquarium backgrounds are a bit cheesy for my taste! Thanks in advance for your suggestions.

I'm thinking grassland background.
